本扩展模块是实验性的。该模块的行为,包括其函数的名称以及其它任何关于此模块的文档可能会在没有通知的情况下随 PHP 以后的发布而改变。我们提醒您在使用本扩展模块的同时自担风险。

swfgradient() creates a new SWFGradient object.

After you've added the entries to your gradient, you can use the gradient in a shape fill with the swfshape->addfill() method.

SWFGradient has the following methods : swfgradient->addentry().

This simple example will draw a big black-to-white gradient as background, and a reddish disc in its center.

例子 1. swfgradient() example

<?php

  $m
= new SWFMovie();
  
$m->setDimension(320, 240);

  
$s = new SWFShape();

  
// first gradient- black to white
  
$g = new SWFGradient();
  
$g->addEntry(0.0, 0, 0, 0);
  
$g->addEntry(1.0, 0xff, 0xff, 0xff);

  
$f = $s->addFill($g, SWFFILL_LINEAR_GRADIENT);
  
$f->scaleTo(0.01);
  
$f->moveTo(160, 120);
  
$s->setRightFill($f);
  
$s->drawLine(320, 0);
  
$s->drawLine(0, 240);
  
$s->drawLine(-320, 0);
  
$s->drawLine(0, -240);

  
$m->add($s);

  
$s = new SWFShape();

  
// second gradient- radial gradient from red to transparent
  
$g = new SWFGradient();
  
$g->addEntry(0.0, 0xff, 0, 0, 0xff);
  
$g->addEntry(1.0, 0xff, 0, 0, 0);

  
$f = $s->addFill($g, SWFFILL_RADIAL_GRADIENT);
  
$f->scaleTo(0.005);
  
$f->moveTo(160, 120);
  
$s->setRightFill($f);
  
$s->drawLine(320, 0);
  
$s->drawLine(0, 240);
  
$s->drawLine(-320, 0);
  
$s->drawLine(0, -240);

  
$m->add($s);

  
header('Content-type: application/x-shockwave-flash');
  
$m->output();
?>
